Answer:
8 pounds of cheaper candy,
17.5 pounds of expensive candy
Step-by-step explanation:
Let's define some variables. Let's say the amount of pounds of candy that sells for $2.20/lb is x, and the $7.30 is y. Now we can write some equations!
x + y = 25.5
We can start substitution. We can say that x = 25.5 - y. Plugging this into our second equation, we get:
y = 17.5
Plugging this in, we find that:
x = 8.

Reduced (simplify) all factions if possible
------------------------------------------------------------------------------------
(1/4 cannot be reduced)
1/4 = 1/4
(divided by 2 for both numerator and denominator)
2/8 = 1/4
(divide by 3 for both numerator and denominator)
3/12 = 1/4
